Tunxi Drunken Crab

Tunxi District in Huangshan has cured crabs in baijiu since the mid-Qing Xianfeng era, when the Ziyun Guan restaurant in Tunxi's old town created it (around 1855), when Huizhou merchants returning home wanted a banquet starter that would keep through winter without refrigeration. The local rule is the cure must use sorghum baijiu of 50%+ ABV, not the milder Shaoxing wine used in Shanghai's drunken crab — the higher proof is what makes the cold-cure safe and gives the meat its custard set rather than the looser texture of Jiangnan-style.

Tunxi District (Huangshan) has cured crabs in 50%+ ABV sorghum baijiu since the late Qing — milder Shaoxing wine of Shanghai's drunken crab won't do it. The high proof denatures protein into a custard set and is the actual safety mechanism; below 40% ABV plus skipped 4°C hold is a parasite vector.

The shell pulls off cool, glossy with cure. The meat isn't cooked — it's set, the way custard is set. Each strand slides off the shell intact and tastes of crab roe, soy, and a slow burn of grain liquor that arrives last. The roe in the body cavity is half-liquid, half-jellied, and saltier than the legs. Eat with white rice congee; never with hot tea, which collapses the texture in your mouth.

Two things happen at once in the jar. The 50%+ ABV liquor denatures crab protein the way heat would — slowly, evenly, without ever cooking it — which is why the meat sets into a custardy gel. But the cure is not a true safeguard against parasites: freshwater crab is an intermediate host for the lung fluke (Paragonimus), whose encysted metacercariae are highly resistant and are not reliably killed by high-proof liquor soaking, however long. Raw-cured drunken crab therefore carries a real risk of parasites and pathogens, which is why many shops now use a cooked-cure version — steaming the crab first, then steeping it. Source matters more than recipe.
